Coking reactor

Abstract

Coking system, wherein the coking blends particularly based on hard coal, are fed batchwise to a reactor (1), which is heated indirectly by heat recovery in regenerators (I, II) or recuperators, whereby the reactor is built as a high-capacity coking reactor (100), several high-capacity coking reactors are combined to form a reactor block and the high-capacity coking reactors are built as mutually independent modules, whereby each module can be operated or optionally replaced independently of the neighboring modules, with little or no impairment of the operation of the neighboring modules. The individual reactors are independently operatable in terms of statics and heat supply. The regenerators, or recuperators (I, II, R, R') can be arranged laterally or underneath the reactor chamber. Neighboring reactors can have a common intermediate wall (2). The reactor chambers have a width of at least 0.7 m, a height of at least 8.5 m and a length of at least 18 m.

We claim: 
     
       1. A coking reactor supplied batchwise with coking blends comprising: a reactor chamber having a width of at least 0.7 m, a useful height of at least 8.5 m and a useful length of at least 18 m;   a flue chamber adjacently positioned plane parallel on either side of said reactor chamber, each of said flue chambers comprising: a stretcher wall adjacent said reactor chamber; and   a partition wall facing opposite and outward from stretcher wall;   one pair of rigid lateral walls encompassing therebetween said flue chambers and said reactor chamber;     an adjustable heating means for supplying hot heating media and heating said reactor chamber indirectly through said flue chambers;   a plurality of regenerator means for recovering heat from the hot heating media; and   separate control means for regulating said adjustable heating means and allowing each of said flue chambers to be independently heated.   
     
     
       2. A coking reactor according to claim 1 wherein one of said regenerator means is positioned between one of said partition walls and one of said rigid lateral walls. 
     
     
       3. A coking reactor according to claim 1 further comprising a roof area above said reactor chamber, said rigid lateral walls being interconnected in said roof area in a rigid manner through spacing elements and longitudinal tie rods. 
     
     
       4. A coking reactor according to claim 1 wherein said rigid lateral walls are provided with cooled tensioned rods. 
     
     
       5. A coking reactor according to claim 1 wherein said stretcher walls have a thickness of at least 50 mm. 
     
     
       6. A coking reactor according to claim 1 further comprising a base plate below said reactor chamber through which said rigid lateral walls are positively connected. 
     
     
       7. A coking reactor according to claim 1 further comprising cross walls and block walls, said cross walls and block walls being connected with one another and having arranged therebetween said regenerator means in a longitudinal direction of said reactor chamber, said cross and block walls being oriented transverse to said rigid lateral walls and allowing transmission of forces from said reactor chamber to said rigid lateral walls. 
     
     
       8. A coking reactor according to claim 1 wherein said plurality of regenerator means comprises two regenerator means positioned between one of said rigid lateral walls and one of said partition walls, said reactor chamber further comprising a longitudinal wall between said one partition and one rigid lateral wall and running in a longitudinal direction of said chamber, said two regenerator means being separated from one another by said longitudinal wall, and said two regenerator means being in communication with one another through a reversing point defined by an end of the longitudinal wall for counterflow of the hot heating media therethrough. 
     
     
       9. A coking reactor according to claim 1 further comprising a vertical duct formed between one of said rigid lateral walls and one of said partition walls, said vertical duct being free of heat-exchanging material and there being only one regenerator means between said rigid lateral and partition walls. 
     
     
       10. A coking reactor according to claim 9 further comprising an insulating layer wall between said regenerator means and said partition wall and a further insulating layer wall between said vertical duct and said regenerator means, said insulating layer wall being thicker in an upper cool area of said regenerator means than in a lower area thereof, and said further insulating layer wall being thicker in said lower area of said regenerator means and thinner in said upper area. 
     
     
       11. A coking reactor according to claim 1 wherein at least one of said regenerator means is arranged underneath said flue chamber. 
     
     
       12. A coking reactor according to claim 1 wherein a plurality of said coking reactors are joined together to form a reactor block, each of said coking reactors forming an individual module, each of said modules being operatable and optionally replaceable independently of any neighboring modules.
